DuoLingo is an excellent resource. Keep working with it. I find the following resources helpful as well:

SpanishDict - videos, flashcards, progressive lessons
LiveMocha - progressive lessons with written and verbal exercises that are reviewed by native speakers. The reviews are only as good as the reviewer, and some are great and others terrible.
Verbling - the ability to chat (video chat or audio only) with native Spanish speakers who are learning English. Also online classes via Google Hangout. Good for listening and speaking but not great for fundamentals (beginners)
News in Slow Spanish - a weekly podcast of news articles in slower, easier to understand, Spanish. You can listen on their website or you can subscribe to their podcast via iTunes and sync it to your iPod. RTVE.es - news articles and videos, radio (channel 5 is all talk, SUPER for practicing listening skills), television programs (though many TV shows are not broadcast in the US - you'll get a message saying copyright law prohibits viewing in your area)
Anki - flashcard application with some amazing free Spanish decks. You can install Anki on your PC, mobile phone, iPad, laptop... and keep all of them synchronized so your progress is not lost between devices.
Kindle - Get the plain old Kindle Touch. It allows you to install a bilingual (Spanish to English) dictionary and then when you read Spanish novels or texts all you have to do is touch the word and you see it translated to English. Makes reading a lot faster and easier, and I find I pick up vocabulary and the "feel" of the language more quickly this way.

I have found these podcasts really helpful with understanding spoken spanish. The coffee break series takes you from beginner to intermediate over 80 episodes, then show time spanish is more upper intermediate (I understood bits, but it was still enjoyable). They currently run a programme called coffee break magazine which is intermediate (easier than show time). I have only used the free material so I cannot comment on the premium stuff, but the free podcasts were great.
